Pumping switching device and concrete pumping equipment
The invention discloses a pumping switching device and concrete pumping equipment, relates to the field of engineering machinery, and aims to optimize the structure of the pumping switching device. The pumping switching device comprises a skirt valve body, a positioning block and a swing shaft; the skirt valve body is provided with a first mounting hole and a second mounting hole; the positioningblock is mounted on the skirt valve body and is positioned between the first mounting hole and the second mounting hole; the positioning block has a first positioning plane. the swing shaft penetratesthrough the first mounting hole and the second mounting hole; the swing shaft has a second positioning plane; and the first positioning plane and the second positioning plane are in surface-to-surface fit. According to the technical scheme, the positioning block and the swing shaft are in surface-to-surface fit through the first positioning plane and the second positioning plane; and the first positioning plane and the second positioning plane are planes. In the using process, the planes are not prone to being abraded and damaged, and therefore the first positioning plane and the second positioning plane can be accurately positioned all the time.
本发明公开了一种泵送切换装置以及混凝土泵送设备，涉及工程机械领域，用以优化泵送切换装置的结构。泵送切换装置包括裙阀阀体、定位块以及摆动轴。裙阀阀体具有第一安装孔和第二安装孔。定位块安装于裙阀阀体，并且位于第一安装孔和第二安装孔之间；定位块具有第一定位平面。摆动轴穿过第一安装孔和第二安装孔；摆动轴具有第二定位平面；第一定位平面和第二定位平面形成面面配合。上述技术方案，定位块和摆动轴之间采用第一定位平面和第二定位平面形成面面配合。第一定位平面和第二定位平面都为平面。在使用过程中，平面不易被磨损破坏，这使得第一定位平面和第二定位平面始终能够保持精准定位。
